35. End the Paper Chase

Americans recycled 42 million tons of paper last year50% of what they usedbut still pulverized the rest. Paper does grow on trees: 900 million of them every year become pulp and paper.

We can reduce that number by buying more recycled paper. It uses 60% less energy than virgin paper. Each ton purchased saves 4,000 kW-h of energy, 7,000 gal. of water and 17 trees, and a tree has the capacity to filter up to 60 lbs. of pollutants from the air.
